Question

Options
1:2
4:5
5:8
8:5
Solution
If a bus travels 160 km in 4 hours and a train travels 320 km in 5 hours at uniform speeds, then the ratio of the distances travelled by them in one hour is 5:8.
Explanation:
Distance travelled by bus in 4 hours = 160 km
∴ Distance travelled by bus in 1 hour = `160/4` km = 40 km
Distance travelled by train in 5 hours = 320 km
∴ Distance travelled by train in 1 hour = `320/5` km = 64 km
∴ The required ratio = `(40 km)/(64 km) = 5/8` = 5:8
